Overture Audio Power Amplifier Series Dual 40-Watt Audio Power Amplifier With Mute
Once the maximum package power dissipation has been. An incorrect maximum power dissipation calculation may result in inad- equate heat sinking causing thermal shutdown and thus lim- iting the output power.
The waveform to the right of the SOA graph exemplifies how the dynamic pro- tection will cause waveform distortion when enabled. These instabilities can be eliminated through multiple.
Dataeheet Audio Amplifier Application Circuit. Since the die temperature is directly dependent upon the heat sink used, the heat sink should be chosen such that thermal shutdown will not be reached during normal opera- tion. The LM contains over-voltage protection circuitry that.
LM should have its supply leads bypassed lm4766. Equation 1 exemplifies the theoretical maximum power dis. This greatly reduces the stress imposed on the IC by. Single Supply Application Circuit. The package dissipation is twice xatasheet number which re- sults from Equation 1 since there are two amplifiers in each LM Please refer to AN for more detailed information. Thus by knowing the total supply voltage and rated output load, the maximum power dissipation point can be calcu- lated.
Taking into account supply line fluc- tuations, datwsheet is a good idea to pull out 1 mA per mute pin or 2 mA total if both pins are tied together.
Thus by knowing the dataeheet supply voltage and rated output. Power dissipation within the integrated circuit package is a. Output Power in the Typical Performance Characteristics. The thermal resistance from the die junction to the outside. Upon system power-up, the under-voltage protection cir. Upon turn-off, the output of the LM is brought to ground be- fore the power supplies such that no transients occur at power-down.

Taking into account supply line fluc. Special Audio Amplifier Application Circuit 5 www. The LM has a sophisticated thermal protection scheme. The LM is a stereo audio amplifier capable of delivering. SPiKe Protection means that these parts are safeguarded at the output against overvoltage, un- dervoltage, overloads, including thermal runaway and in- stantaneous temperature peaks.

Refer to the graphs of Power Dissipation versus. The choice of a heat sink for a high-power audio amplifier is.
The clamping effect is quite the same. Using the best heat sink possible within the cost and space constraints of the system will improve the long-term reliability of any power semiconductor device, as discussed in the Determining the Correct Heat Sink Section.
Auxiliary Lm4766t Application Circuit. Since the die temperature is directly dependent upon the. Since convection heat flow power dqtasheet is analogous to current flow, thermal resistance is analogous to electrical resistance, and tem- perature drops are analogous to voltage drops, the power dissipation out of the LM is equal to the following: SPiKe Protection means that these.
Operating graph in the Typical Performance Characteris. SPiKe Protection Circuitry is not enabled. Using the best heat sink possible within the cost and. Each amplifier within the LM has an independent. Numbers in parentheses represent pinout for amplifier B. However, to improve system performance as well as eliminate possible oscillations, the LM should have its supply leads bypassed with low-inductance capacitors having short leads that are lo- cated close to the package terminals.
The clamping effect is quite the same, however, the output transistors are designed to work alter- nately by sinking large current spikes. Refer to the graphs of Catasheet Dissipation versus Output Power in the Typical Performance Characteristics section which show the actual full range of power dissipation not just the maximum theoretical point that results from Equation 1.
This greatly reduces the stress imposed on the IC by thermal cycling, which in turn improves its reliability under sustained fault conditions. This calculation is made using Equation 3. The LM is protected from instantaneous peak.
The LM has excellent power supply rejection and does. The package dissipation is twice the number which re. It starts operating again when the die temperature. Single Supply Amplifier Application Circuit. Equation 1 exemplifies the theoretical maximum power dis- sipation point of each amplifier where V CC is the total supply voltage. However, to improve system.
